Today I get to re-visit the Microlab brand 3 years later and see the fruits of their labor with one of their latest portable Bluetooth speaker systems called the MD312. The MD312 sports a unique Moon-shaped shell design offered in multiple color choices, offers 4-Watt of RMS continuous power, a replaceable rechargeable Lithium-ion battery, and comes in a 2.1 configuration inside a single compact package."
